simple java math script needed

I am NOT a php or java programmer. I am looking for a complete solution.

I need script that asks a question like "What do you charge for blah blah"
The user enters a dollar amount.
The script then does math based on the number entered.
The script math is a number I hard code into the script/user entered number.
Example:
User enters 125
My hard coded number is 250
Math would be 250/125

The script would then return: "Your result (or words that I would put in) is " 2 (the result of the math)

thanks.

No...homework ended decades ago.

That works fine, thanks.
I would like to round the decimals to 2, however.
